Release a yo-yo and follow the unwinding string

Original, untested video brief. No input image or generated result is supplied.

1. Task and boundary

Release one partly wound yo-yo from the original supporting hand while its upper string end remains fixed in the other hand. Follow the body descending as it turns and the free string span lengthens. End near the bottom of the available string with the same body still attached.

This original motion brief is untested. Use a simple fixed-axle visual arrangement with a short readable string. Exclude trick instructions, return-to-hand claims, sustained sleeping, exact rotation rates and a detached body falling independently.

2. Authorized first frame

Prepare a photograph or accurate drawing you own or have permission to use. Show one yo-yo with some string still visibly wound at its axle. One original hand supports the body while the other holds the upper string end above it.

Choose a slightly oblique side view that reveals both the marked front disc and the axle gap. Leave enough vertical space below for the entire descent. Keep the string distinct from the background and avoid tangled loops or hidden upper attachments.

3. Use the generator

Open the current image-to-video generator in a mode accepting your authorized first frame. Paste the prompt; check settings and cost before submission. Nothing runs automatically.

4. Prompt and timing

Begin with my authorized image of one partly wound yo-yo supported by the original lower hand, with its upper string end held by the other hand. Lock the camera and upper hand position. Open the supporting fingers and move them clear. Let the same yo-yo descend while rotating in the direction that releases its existing axle wraps. The straight free span above it lengthens as visible string leaves the winding, with the upper endpoint stationary. Keep the body, axle and marked disc intact and the string connected throughout. As the available wound length finishes paying out, let the descent slow into a brief supported settling at the bottom. Hold without returning to the hand. No new string, loose falling disc, rewinding trick, extra yo-yo, camera tracking, cut or lettering.

Establish, first fifth: identify the held upper end, wound axle and supporting fingers.
Descend, middle three fifths: follow support release, body rotation and growing free string together.
Settle, final fifth: inspect the attached body near the bottom of the paid-out string.

5. Inspect the output

For each check, record a frame or time, observation and pass, fail or inconclusive judgment.

The lower fingers release before the main descent begins.
The upper string endpoint remains fixed while the yo-yo center moves down.
The marked disc turns as string pays out from its existing axle region.
The free span grows continuously rather than appearing fully extended in one frame.
The final body remains attached and does not begin a return trick.
If the axle is hidden, mark rotation-to-unwinding correspondence inconclusive.

6. Fix one failure

The body drops without turning: keep the front mark readable and couple descent to unwinding.
The upper hand follows it: anchor that hand against a fixed background reference.
Extra string appears: retain a visible departure from the existing wound region.
The body detaches at the bottom: preserve its final axle connection.
The action becomes a trick loop: end after the first descent and brief settling.

7. Ending and limits

Finish near the bottom of the available string with the original yo-yo attached beneath the unchanged upper endpoint.

Save your result, authorized input, exact prompt, settings and inspection notes.

No H3 result, drop experiment, angular-speed estimate or yo-yo performance guarantee is supplied. The final settling is a visual target, not a prediction of bounce or real axle behavior.

The fixed-spool task holds the spool center still while a free end moves. Here the upper end stays fixed while the rotating wound body itself descends, changing which part carries the motion.
